Okay, I just tried and was unable to get this on my side.
Are you able to replicate the issue - meaning, if you close the game, load a save and try again does it still happen?
If so, please do the following steps:
- Open the cmd on the folder with the game (you can do this by going to the top bar with the path on the file explorer and typing cmd)
- Run .\ModificationApp.exe (This should open the game, while keeping the command line window)
- Load the save, play the event until the floor with the missing artwork.
What messages shows up in the cmd window?
Any error message? If so please paste the error message here.
